Key legal question
Admissibility of the public-law appeal against the revocation warning and family reunification refusal
Extracted holding
The appeal was admissible against both the revocation warning and the family reunification refusal, but only the Federal Administrative judgment could be challenged.
Extracted reasoning
A continued residence permit generally exists, so the warning is appealable; the spouse could in principle claim a permit under Art. 43 AuG, making judicial review available. The cantonal government's decision was not the object of review.
